Il me semble que l'idée est plutôt que le mode de connexion devient identique pour tout le monde, quelle que soit la localisation du terminal.

Virtual private network
From Wikipedia, the free encyclopedia
A virtual private network or VPN for short, is a way of connecting a computer to a remote network. Most people using computers connect to the World Wide Web using a normal network - they use dial-up or broadband. A VPN is a little bit different. It's used by some workers to connect using a laptop to do work - they can check their work email and see work websites which can not be seen on the normal internet.[1]
VPN offers often anonymity by hiding the user and making it very hard for anyone to track them.[2]
Recently VPN is often used to access to the websites blocked in some countries, like China
https://simple.wikipedia.org/wiki/Virtual_private_network

A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus are benefiting from the functionality, security and management policies of the private network.[1] A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption.
A VPN spanning the Internet is similar to a wide area network (WAN). From a user perspective, the extended network resources are accessed in the same way as resources available within the private network.

Réseau privé virtuel
En informatique, un réseau privé virtuel, quelques fois abrégé RPV au Québec1 et VPN ailleurs, de l'anglais Virtual Private Network, est un système permettant de créer un lien direct entre des ordinateurs distants. On utilise notamment ce terme dans le milieu de la dématérialisation fiscale et dans le travail à distance, ainsi que pour l'accès à des structures de type cloud computing.
Fonctionnement
La connexion entre les ordinateurs est gérée de façon transparente par le logiciel de VPN, créant un tunnel entre eux. Les ordinateurs connectés au VPN sont ainsi sur le même réseau local (virtuel), ce qui permet de passer outre d'éventuelles restrictions sur le réseau (comme des pare-feux ou des proxys).
Intérêt
Un VPN permet d'accéder à des ordinateurs distants comme si l'on était connecté au réseau local. On peut ainsi avoir un accès au réseau interne (réseau d'entreprise, par exemple).
Un VPN dispose généralement aussi d'une passerelle permettant d'accéder à l'extérieur, ce qui permet de changer l'adresse IP source apparente de ses connexions. Cela rend plus difficile l'identification et la localisation approximative de l'ordinateur émetteur par le fournisseur de service. Cependant, l'infrastructure de VPN (généralement un serveur) dispose des informations permettant d'identifier l'utilisateur. Cela permet aussi de contourner les restrictions géographiques de certains services proposés sur Internet.

Why you want a VPN
You have at least four great reasons to start using a VPN. First, you can use it to connect securely to a remote network via the Internet. Most companies maintain VPNs so that employees can access files, applications, printers, and other resources on the office network without compromising security, but you can also set up your own VPN to safely access your secure home network while you're on the road.
Second, VPNs are particularly useful for connecting multiple networks together securely. For this reason, most businesses big and small rely on a VPN to share servers and other networked resources among multiple offices or stores across the globe. Even if you don't have a chain of offices to worry about, you can use the same trick to connect multiple home networks or other networks for personal use.
Third, if you're concerned about your online privacy, connecting to an encrypted VPN while you're on a public or untrusted network—such as a Wi-Fi hotspot in a hotel or coffee shop—is a smart, simple security practice. Because the VPN encrypts your Internet traffic, it helps to stymie other people who may be trying to snoop on your browsing via Wi-Fi to capture your passwords.
Fourth and finally, one of the best reasons to use a VPN is to circumvent regional restrictions—known as geoblocking—on certain websites. Journalists and political dissidents use VPNs to get around state-sponsored censorship all the time, but you can also use a VPN for recreational purposes, such as connecting to a British VPN to watch the BBC iPlayer outside the UK. Because your Internet traffic routes through the VPN, it looks as if you're just another British visitor.

There are 2 main ways of sharing your VPN connection: using a flashed router or sharing your computer’s internet connection.
:
To share your VPN connection through your Windows or Mac device is fairly easy. All you need is a VPN account, your PC connected to the internet through WiFi or Ethernet (adapter required for Mac) and your media device plugged into your PC with an Ethernet cable.

Using ICS (Internet Connection Sharing)
If you want to share one Internet connection among several computers, you have two options:
• Use Internet Connection Sharing (ICS).
• Use a router.
How does ICS work?
First, you'll need one computer, called the host computer, that's connected to the Internet and that has a separate connection to the other computers on your network. You'll enable ICS on the Internet connection. The other computers on your network then connect to the host computer, and from there to the Internet through the host computer's shared Internet connection.

To prevent their IP-addresses from being visible to the rest of the Internet, millions of people have signed up to a VPN service. Using a VPN allows users to use the Internet anonymously and prevent snooping.

After intensive discussion and searching we can now translate the phrase "Le VPN station de travail banalise le raccordement de ces terminaux au SI" accordingly:

“The VPN workstation (workstation providing VPN access) banalises (caches/hides/makes invisible) the connection of these terminals to the internet server” or shorter:
The VPN server banalises the terminals connected to the internet server”.
